The digital identity device 105 c verifies and authenticates all communications between the systems 100. The GRID 905 is the universal keeper of all digital identity devices 105. If a digital identity device 105 is lost, the information within the digital identity device 105 is secure. Only the registered owner of the digital identity device 105 can extract the information within the digital identity device 105. Lost digital identity devices 105 are mailed to the administrator of the GRID 905 and are returned to the owner. The GRID 905 has minimal low security information that is not encrypted, such as name and address tied to the external markings of the digital identity devices 105 or to the microprocessor identity devices 205, to enable this function.

The communication links 910 couple the GRID 905 and the systems 100 to the Internet.

In step 1205, the first licensee computer 1105 a initiates the installation process by downloading the software program 1120 via the connection 1115. The installation process is automatically initiated by the downloading process.

In an alternate embodiment, the first licensee computer 1205 a initiates the installation process by running a setup program within the software program 1120.

In step 1210, the first licensee computer 1105 a sends the microprocessor identity information 230 of the microprocessor identity device 205 a and the license key 1125 to the vendor computer 1110 via the connection 1115. The license key 1125 issues to the first licensee computer 1105 a during step 1205. The software program 1120 licenses to the first licensee computer 1105 a.

In an alternate embodiment, the software license key 1125 issues on the software media or a container for the software media.

In an alternate embodiment, the first licensee computer 1105 a sends the microprocessor identity information 230 of the microprocessor identity device 205 b and the license key 1125 to the vendor computer 1110 via the connection 1115. The software program 1120 licenses to the digital identity device 105.

In step 1215, the vendor computer 1110 verifies the microprocessor identity information 230 from the first licensee computer 1105 a. The vendor computer 1110 confirms the presence of the license key 1125 in the software key database 1140 to determine if the license key 1125 is valid. The vendor computer 1110 further determines if the license key 1125 is already coupled in the software key database 1240. If coupled, there may be a breach of the licensing agreement. The vendor computer 1110 requests alternate microprocessor identity information 230 from the first licensee computer 1105 a and establishes multiple links to the license key 1125. In an alternate embodiment, the vendor computer 1110 halts the method 1200 if the license key 1125 is coupled. In an alternate embodiment, the vendor computer 1110 chooses to halt the method 1200 and take actions outside this automated licensing method 1200.

In step 1220, the vendor computer 1110 binds the license key 1125 to the microprocessor identity information 230.

In an alternate embodiment, the license key 1235 is encrypted using the microprocessor identity device 205 a.

In step 1225, the first licensee computer 1105 a completes the installation of the software program 1120. The first licensee computer 1105 a also stores the bound microprocessor identity information 230 and the license key 1125 from step 1220.

In an alternate embodiment, if the licensee agreement allows, a second licensee computer 1105 b installs the software program 1120 from the first licensee computer 1105 a using the method 1200. The software key database 1140 associates the microprocessor identity information 230 of the microprocessor identity device 205 a, 205 b, or 205 c to the license key 1125. The association of the license, whether to the first licensee computer 1105 a or the digital identity device 105, is determined by the licensing terms of the software program 1120.

In an alternate embodiment, the method 1200 applies to other types of intellectual property, such as MP3 music, which runs on computers with microprocessor identity devices 205.

Referring to FIG. 13, a method 1300 for de-licensing software includes: in step 1305, de-installing software; in step 1310, verifying the license status; in step 1315, un-binding identity device and software license key; and in step 1320, completing de-installation. The method 1300 is the logical reverse of the method 1200.

In step 1305, the first licensee computer 1105 a starts the de-installation of the software program 1120. The software program 1120 is de-installed using a standard de-installation program supplied by the vendor. The first licensee computer 1105 a transmits the license key 1125 and the microprocessor identity information 230 to the vendor computer 1110 via the connection 1115.

In an alternate embodiment, the first licensee computer 1105 a sends the microprocessor identity information 230 of the microprocessor identity device 205 b and the license key 1125 to the vendor computer 1110 via the connection 1115.

In an alternate embodiment, the second licensee computer 1105 b sends the microprocessor identity information 230 of the microprocessor identity device 205 c and the license key 1125 to the vendor computer 1110 via the first licensee computer 1105 a.

In step 1310, the vendor computer 1110 verifies the binding of the license key 1125 and the microprocessor identity information 230 in the software key database 1140. If the license key 1125 and the microprocessor identity information 230 do not match the values stored in the software key database 1140, the vendor computer 1110 halts the method 1300. In an alternate embodiment, there are other corrective actions the vendor computer 1110 may take to correct an exception to its licensing agreement.

In step 1315, the vendor computer 1110 un-binds the license key 1125 to the microprocessor identity information 230 in the software key database 1140. The software key database 1140 un-associates the microprocessor identity information 230 to the license key 1125. The software key database 1140 leaves a blank field for the microprocessor identity information 230.

In step 1320, the vendor computer 1110 completes the reinstallation process by updating the software key database 1140. The first licensee computer 1105 a removes the software program 1120.

In an alternate embodiment, the second licensee computer 1105 b performs the method 1300 to de-install the software program 1120. The method 1300 de-installs the software from the second licensee computer 1105 b, but not the first licensee computer 1105 a (such as in a private network).

In a networked environment, the methods 1200 and 1300 are done on an individual computer basis, especially when software resides on the computers in which they are used.

Referring to FIG. 14, a method 1400 for tracking software usage includes: in step 1405, starting the software; in step 1410, creating usage information; and in step 1415, transmitting the usage information. Tracking software usage determines licensing fees by the vendor computer 1110. The method 1400 assumes the first licensee computer 1105 a has already performed the method 1200.

In step 1405, the first licensee computer 1105 a starts and uses the software program 1120.

In step 1410, the software program 1120 creates usage information. The usage information may include, for example, start time, stop time, and users.

In an alternate embodiment, the usage information is stored in a file on the first licensee computer 1105 a.

In step 1415, the first licensee computer 1105 a transmits the usage information to the vendor computer 1110 via the connection 1115.

In an alternate embodiment, the first licensee computer 1105 a transmits the file of the usage information when the connection 1115 is in place. The first licensee computer 1105 a further deletes the file after transmission to prevent backlogs of old files.

Although illustrative embodiments of the invention have been shown and described, a wide range of modification, changes and substitution is contemplated in the foregoing disclosure. In some instances, some features of the present invention may be employed without a corresponding use of the other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention.
